mail server settings for activiti explorer

[gurolakman]

I created a simple flow comprising a single "send mail task" under Eclipse and tested its behavior successfully after configuring the mail server properties in an associated <activiti.cfg.xml> file as follows:

<property name="mailServerHost" value="smtp.gmail.com" />
<property name="mailServerPort" value="465" />
<property name="mailServerUsername" value="…" />
<property name="mailServerPassword" value="…" />
<property name="mailServerUseSSL" value="true" />

I then deployed the same flow on the activiti explorer (portal), configured the <engine.properties> file for activiti-explorer as follows, and wanted to test its behavior once again (i.e., by starting the flow manually from the portal).

engine.email.enabled=true
engine.email.host=smtp.gmail.com
engine.email.port=465
engine.email.username=…
engine.email.password=…
engine.email.usessl=true

Unfortunately, I failed to get my flow to work properly (i.e., the email send attempt to smtp.gmail.com:465 timed out).

I'm wondering if this failure may be triggered by the "engine.email.usessl" property setting above and whether the property name is valid. I wasn't able to find a comprehensive list of valid <engine.email.*> properties in the user guide.

Any insight will be greatly appreciated.

Hi,
You could start investigating into this class: MailActivityBehavior

find this line:
email.setSSLOnConnect(processEngineConfiguration.getMailServerUseSSL());
and check if the values set into the email object are correct.

As i know google also needs TLS = true
<code>
<property name="mailServerUseTLS" value="true" />
</code>

Hi,

I had a similar problem. The documentation and naming of properties are somewhat inconsistent using Spring Boot, I had to use <java>mailServerUseTls</java> (camelCase) instead of <java>mailServerUseTLS</java>. Maybe worth a try I guess.

Thank you both for your suggestions. After further reading and some more investigation, I decided to remove all e-mail server related settings (including advanced mail settings around SSL/TLS use) that I inserted earlier in the engine.properties files (for activiti-exporer and activiti-rest) and move them into the following files:

./webapps/activiti-explorer/WEB-INF/classes/activiti-custom-context.xml
./webapps/activiti-rest/WEB-INF/classes/activiti-custom-context.xml

as part of org.activiti.spring.SpringProcessEngineConfiguration. Subsequently, I was able to send mail properly. So, my issue seems to be resolved. Once again, thanks.

Hi gurolakman,
I'm happy you solved it.
i'm sure it will be useful to the community to close this thread in a "Open Source" way so the other people interested in this could benefit from that.

so what do you think about sharing to the community the settings you did for gmail ? (don't forget to mask your passwords and account name )

Most certainly Attached pls find copies of the config files that I used for activiti-explorer and activiti-rest, respectively.
